Answer:C - Planning Stage
Explanation: The System Development Life Cycle is a model of which organisations use when developing a new system.
SDLC has 5 Phases or steps and they include:
- Planning
- Analysis
- Design
- Implementation
- Maintenance
Each stage of SDLC has its importance in the system development.
Planing: At this state, the problem is identified, options of solutions are given and analysed as well as the possible outcomes are considered.
Analysis: At this stage the various options given at the planning stage are analysed and validated
Design: At this stage, the analysed options are designed to give a logical evaluation of the model to be adopted
Implementation: At the state, the design is implemented and tested
Maintenance: At this state, the errors are corrected and validated.
Answer:
The answer is True.
Explanation:
A decision tree, usually, always begins with a single node and then branches into possible outcomes. Each of these results creates additional nodes, which branch into other established possibilities. This gives a shape similar to that of a tree.
<span>Mean absolute deviation, standard deviation and variance are all measures of the variability of a data set. The absolute and mean absolute deviation display the quantity of deviation or variation that arises about the mean score. To discover the total variability in our group of data simply add up the deviation of each score from the mean. The average deviation of a score can then be considered by dividing the total by the number of scores. To calculate the deviation of a score from the mean rest on on choice of statistic whether by means of absolute deviation, variance or standard deviation.</span>
